OC shows this when I boot USB:
OCS: No schema for Base at 0 Index. context Patch
OCS: No schema for BaseSkip at 1 Index. context Patch!

OCS: No schema for ForcebooterSignature at 8 Index. context <Quirks>
OCS: No schema for AppleInput at 1 Index. context UEFI

This fix later.

Boot in verbose mode and post screenshot before laptop reboot.
 
Well I erased disk and fresh installed Big Sur, it works good, but I still need to fix bluetooth and touchscreen (wifi works, card is DW1560)
 
Did you do that?

DW1560 & DW1830​

Users with one of these two cards first need to disable the intel kexts:

  • EFI/OC/Config.plist > Kernel > Add > Airportitlwm > Enabled = No
  • EFI/OC/Config.plist > Kernel > Add > IntelBluetoothInjector > Enabled = No
  • EFI/OC/Config.plist > Kernel > Add > IntelBluetoothFirmware > Enabled = No
Then enable the corresponding kexts for those two cards:

  • EFI/OC/Config.plist > Kernel > Add > AirportBrcmFixup > Enabled = Yes
  • EFI/OC/Config.plist > Kernel > Add > AirPortBrcm4360_Injector > Enabled = Yes
  • EFI/OC/Config.plist > Kernel > Add > BrcmBluetoothInjector > Enabled = Yes
  • EFI/OC/Config.plist > Kernel > Add > BrcmFirmwareData > Enabled = Yes
  • EFI/OC/Config.plist > Kernel > Add > BrcmPatchRAM3 > Enabled = Yes
 
I fixed it using DW1820a instructions.
Touchscreen works too, I cleared NVRAM and it worked.

Thanks a lot.
 
Great!
 
Can I update to last Big sur update with this OC config and version?
 
Would this EFI work for the T440P as well?
I used your High Sierra guide back in the day and it worked great.
